Abstract

Abstract Au–Pt alloy nanoparticles have been synthesized by the reduction of tetrachloroauric acid (HAuCl 4 ) and chloroplatinic acid (H 2 PtCl 6 ) using sodium borohydride in water-in-oil (w/o) microemulsion of water/Triton X-100/cyclohexene/1-hexanol at 25 ± 2 °C. The observed nanoparticles looked like a chain with diameter of 2.5 nm. The particles formation was characterized by UV–visible spectrometry and transmission electron microscopy images. The particles are crystalline confirmed by high-resolution transmission electron microscopy and diffraction pattern. A bright-field and dark-field images were compared to find out the nature of the nanochains.
